I think I hit this problem, but with the 256 GB Lite-On (or LiteOn) NVMe M.2 PCIe CX2 Series Enterprise Solid-State Drive Model CA1-8B256 that came standard in my 2017 Dell Precision Tower 3420.
I'm on the HWE Kernel with the "linux-generic-hwe-16.04" package, having installed from the Ubuntu 16.04.2 LTS amd64 ISO file. I didn't notice any file system errors until I upgraded to the "linux- image-4.8.0-53-generic" package on May 25, 2017. Below is my upgrade schedule showing when the errors occurred: 2017-04-04 Upgraded to 4.8.0-46.49 2017-04-24 Upgraded to 4.8.0-49.52 ← Adds NVMe APST support (LP: #1664602) 2017-05-01 Upgraded to 4.8.0-51.54 2017-05-16 Upgraded to 4.8.0-52.55 2017-05-25 Upgraded to 4.8.0-53.56 ← Started noticing errors on NVMe drive First my Thunderbird Lightning calendar database got corrupted so I couldn't add events. One time the system just froze, with the mouse cursor and keyboard not working. Yesterday, the root file system remounted read-only after waking from suspend. This morning I added "nvme_core.default_ps_max_latency_us=0" to the Grub configuration, and after repairing the file system errors with "e2fsck", everything seems to be working fine so far: /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="quiet splash swapaccount=1 nvme_core.default_ps_max_latency_us=0" I'm considering moving back to the GA 16.04 kernel, just to be more conservative in my system updates. Is the general advice to use the HWE kernel only if we need support for some new hardware, but otherwise, stay on the GA kernel? Is there anything in Kernel version 4.8.0-53 that may have caused the problem or made it more likely to appear? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1678184 Title: APST quirk needed for Samsung 512GB NVMe drive Status in linux package in Ubuntu: Confirmed Status in linux source package in Yakkety: Fix Committed Status in linux source package in Zesty: Fix Committed Bug description: APST support just landed in the latest Zesty kernel (4.10.0-14.16) as part of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1664602. That patch has a quirk for certain 256GB Samsung drives found in Dell laptops that do not behave well when APST is enabled. I am experiencing the same symptoms with the same model laptop except with a 512GB Samsung. Prior to manually disabling APST the drive would die and system would go down in flames with I/O errors within 20 to 40 minutes of boot. $ sudo nvme list Node SN Model Namespace Usage Format FW Rev ---------------- -------------------- ---------------------------------------- --------- -------------------------- ---------------- -------- /dev/nvme0n1 ************** PM951 NVMe SAMSUNG 512GB 1 500.20 GB / 512.11 GB 512 B + 0 B BXV76D0Q ProblemType: Bug DistroRelease: Ubuntu 17.04 Package: linux-image-4.10.0-14-generic 4.10.0-14.16 ProcVersionSignature: Ubuntu 4.10.0-14.16-generic 4.10.3 Uname: Linux 4.10.0-14-generic x86_64 ApportVersion: 2.20.4-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ajclayton 3305 F.... pulseaudio CurrentDesktop: Unity:Unity7 Date: Fri Mar 31 09:42:38 2017 InstallationDate: Installed on 2012-09-08 (1665 days ago) InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Release amd64 (20120425) MachineType: Dell Inc.
